LookiI1g I10W at Figures through 7 the ganle piece Will be seen to comprise a cy1indrica1 member 32 having a b01'e 34 axially extending therethrough vvith 9 10Wel reduced dianeter portion at 36- The upper end of the bo e 3 is threaded, at 8, for receiving the spring retainer 4D vith the spring retainer 4 being fornled of n1agneic materia1.-

''1e 10vver end of the cy1indrica1 nleInber 32 is provided with a plurality of projections 42 a'nd a !rletallic disk of Inagnetic Inateria1 44 is en gaged with the botton1 face of the cy1indrical 1Tlenlber 32 and has a plurality of openings forlned therein for receiving the projections #2.

'I1e projections 42 are then peened to Tetail1 the disk 44 0n the cy1indrical member 32' The disk 44 is also provided vvith a centra1 aperture s for a purpose to be hereinafter described Disposed within the -bore of 'the 'cy1indr cal member 32 iS ai cha'lk means which "is com p'ised of a cup-1ike element 48 having a ange 50, a conventional piece 0f chalk 52having one end received in th cu -1ike element 48. The ange5 is adapted to abut against the shou1der 54 forned between the bore 3 and the reduced diameter porti011 3E The chalk piece 52 extends outwardly through the reduced' diaIneter bore 36 and the ope!ling 46 in the disk 44.

compression spring of coil form 56 is disposed within the bore 34 and engages the Spring retainer 4| at one end and the flange 5 at the other end, inter!!1ediate portions of the spring e10ircling the cup-1ike eleent 48- The directiona1 arrow |3, Shown best in 1'igure 8, is 00Inprised -0f an arfowhead 58 and a vvire su i11tegra11y secured thereto 'he wire s' isof angu1ated forn1 consisting of a `plurality of V-Shaped sections 62. 'he wire G| is of readily bendable Inateria1 Whereby the direction of travel can be indicated as following an arc, 0r, if'de sired, as a* sharp shift in direction Th directiona1 arrow l3 is adapted to be disposed on the upper face of the cy1indrica1 nlen1- ber 32, With an intermediate portion of the wire GI bei11g disposed over the retainer 4u for nlagnetic retention thereby In the nlodiiied form shown in Figure -9) the retaining eletnent is provided with a spring clip Which is adapted to receive ...an intermedia'te portion of (;1e vvire e f01` retaining the arrovv l3 On the cylindrical member 3z.

In the forn1 0f the invention shown in igureS 4 through 6 the retainer ll can be removed by inserting 9 t001 in the holes 4 vvhereas i11 the form shown in Figure 9 the Tetainer can be removed by rotatil1g the s'pring clip 11 view of the foreg0ing, it is be1ieved that a device has been r0vid d whiph wi11 cpoInplish all of tHe Objct' hefeinabove'set dTh Iaving thus described the invention, what is claned as new is: A game piece comprising a cy1indrica body havin u per and 10Wer ends and provided with an aXi1 bore including a screvv-threaded upper portioI1'and an annular shoulder adjacent the hreaded portion of 'sajid 00re, a' resilient claTnp pfovided on the top of aid plug a pointer positioned dian1etrica11y on the upper end of said body andhaving an intenediate portion thereof frictiona1ly engaged by Said` claInp, a cOnlpessiOn spring posiioned in said bore and abutting said plug With its upper end, an inverted cup provided in the 10Wer portion of Said spring and having an outturnedn1argina1 flnge a't its 1ovver edge en gageable with said shoulder, a-diSc-Shaped nlagne provided ai the 10Wer end of said body, keeper pins projecting fron1 he 10Wer end of the body and secured in apertures foned`in said Inagnet; said Inagnet having a centra1 0pening in register with said bOe and a chalk rnounted in said cllp aind projecting downwardly through the opening me of this pate t:
